Oddly, it works really well for me.

When I tried the Nokia PC Suite's sync tool, it got confused by my repeating appointments (e.g., class on Mondays and Wednesdays), and it freaked out at the large size of my contacts list. I already have a subset of my contacts tagged "Sync", which I was able to convince the Ericsson software to pay attention to. There appears to be no comparable setting on the Nokia software.

The Nokia software seems like it was designed to work in "simple" cases, but not to act as a general tool for people with complex Outlook databases.
